Design and Planning of Wireless Communications Networks to Minimize the Construction Cost: An Approach Using Genetic Algorithm-A Proposed Formulation

Abstract

In this paper, we consider the optimal wireless communications network design problem with respect to carrier-to-interference ratio constraints, user demand constraints, and cell capacity constraints. Major components of costs when constructing a wireless communications network are identified, including the costs of acquiring the cell site and installing the base station, the cost of allocating the MTSOs (Mobile Telephone Switching Offices), the cost of connecting the base stations and the MTSOs, and the license costs for permission to use designated frequency spectrum in a given region. In addition, a mathematical programming model is derived to determine the system configuration with minimum construction cost. We truly hope that the proposed algorithms could be practically applied to the unsolved overall wireless network design problem faced by wireless communications network designers today.
